This plugin replaces jar build path entries with project build path entries between maven projects in the Eclipse workspace.

When using maven projects in conjunction with Eclipse it is often necessary to execute mvn eclipse:eclipse after an update. This has the unfortunate side-effect of regenerating the classpath form scratch, which means any project references that were configured in Eclpse get replaced with maven artifact jar references. MvnLink performs the reverse, it searches through classpaths of projects and looks for any reference to a maven artifact jar, and then tries to replace it with a matching workspace project.

See MvnLink Eclipse Update Site link on the right. Once installed MvnLink top level menu will become available. Select MvnLink/Link Projects and project dependencies will be updated.
